Warning
The variant of the bp peering gossip protocol in v1.2.0-rc1 is unsupported and will be superceded by 1.2.0-rc2.
v1.2.0-rc1 introduces a major advancement in peer-to-peer networking with the rollout of a gossip-based block producer auto-peering system. This feature enables block producers to dynamically discover and connect with each other, forming a resilient consensus mesh that adapts to changes such as new node deployments, protocol hard fork upgrades, or ranking shifts — eliminating the need for manual connection configuration.
Notable Changes
Gossip-Based Auto-Peering for Block Producers
Introduces automated discovery and connection among block producers using a gossip protocol, enhancing network resilience and reducing manual configuration.
Elimination of Duplicate P2P Connections
Enhances network efficiency by preventing redundant peer connections, ensuring optimal resource utilization.
Expanded P2P Buffer Sizes
Increases send and receive buffers to 1MB, improving throughput and reducing latency in peer communications.
Enhanced Peer Logging Options
Configurable peer log formats, Provide more flexibility and clarity in monitoring peer interactions.
Snapshot Information Utility
Added a spring-util command to print snapshot information.
